Title: Sideband separating type carrier recovery circuit
Inventor: KIUCHI HITOSHI
IPC: H04L27/22
Filed: 1986-10-14
Abstract: PURPOSE:To obtain a recovered carrier signal phase-locked with a carrier without degrading S/N by constituting the titled circuit so that both sidebands of the carrier of a PSK modulation signal are separated, a phase difference is detected from the difference of both bands to form a phase synchronizing loop. CONSTITUTION:The upper and the lower sideband waves of a carrier wave are assumed to have amplitudes of Au, Al, and the frequency and phase shiftings of the frequency of a voltage controlled oscillator and the carrier wave are assumed to be omegad, phi. The output signal of a mixer 5, and the output signal of a mixer 2 respectively expressed by equations I and II; lower sideband wave after passing through an adder 7 and a LPF 9 comes to be as an equation III, while the upper sideband wave through a subtractor 8 and a LPF 10 comes to be as an equation IV, hence the higher frequency components are eliminated. The frequency and phase differences between the upper and lower sideband waves are twice those between the carrier wave frequency and the voltage controlled oscillator 16. Therefore, by forming the phase loop by using the differences between the upper and lower sideband waves, the above said difference can be made zero, and thus the output of the oscillator comes to a signal whose phase is locked with the output of the carrier of a PSK-modulated signal.

Title: Cathode ray tube
Inventor: IMANISHI WATARU
IPC: H01J29/94
Filed: 1983-12-21
Abstract: PURPOSE:To raise sharply the dielectric breakdown voltage of the glass in the neck of a cathode ray tube by coating a portion of the spacer to support the electron gun structure, which is to be in contact with the inner wall of the neck, with polyimide resin. CONSTITUTION:The tip of a spacer 20, which is opposite to an inner wall 4a of the neck, is coated with polyimide resin 30, and contacts the inner wall 4a of the neck through this polyimide resin 30 and supports an electron gun structure 9. Since the spacer 20 which requires a strong elastic force does not contact an inner conductive film 5, even when a vibration occurs at the time and after the electron gun structure 9 is inserted into the neck 4 during the manufacturing process of a cathode ray tube, the inner conductive film 5 will never be scatched by the spacer 20, and therefore the good dielectric characteristics will be obtained. In addition, even when a metallic element 23 with an earth potential approaches, a portion of the mask 4 opposite to the tip of the spacer will not be subjected to a high voltage electric field, causing no cracks on the glass of the neck.

Title: Ceramic composite wiring board with nickel thin layer
Inventor: MINAGAWA KAZUYASU
IPC: H05K1/09
Filed: 1990-09-13
Abstract: PURPOSE:To obtain a wiring board having excellent fine wiring forming characteristic by plating a thin layer of nickel which is closely placed in contact on a substrate with a conductive metal and improving a bonding force between a conductive metal and nickel thin layer. CONSTITUTION:When a nickel layer is formed on the surface of a metal foil supporting material such as a copper foil having the fine projected and recessed rough surface by the non-electrolytic nickel plating, a layer has the uniform thickness long the rough surface of the supporting material. After laminating a resin, a nickel thin layer is also transferred, simultaneously with formation of the projected and recessed shapes of the metal foil supporting material, to the surface of substrate from which only the supporting material is etched. In the successive processes, this nickel thin layer plays a role of (l) catalyst core for non electrolytic plating and (2) base metal layer for electric plating, and moreover the close contact area between a metal layer formed by the plating and resin gives a strength enough for the close contact force during lamination under the heated and pressurized condition. Therefore, a printed wiring board having a large bonding force for the plated metal can be obtained by forming a circuit through the plating of a metal layer up to the desired thickness on the nickel thin layer.
